CARING FOR CITRINE
Due to citrine's hardness, it is important to protect softer stones from being scratched.
Similarly, you will want to prevent scratches to your citrine from harder gems (sapphire, diamonds, etc.). Therefore, it is a good idea to keep your citrine separate from all other gems of different hardness in a fabric-lined compartment of a jewellery box. Individual cloth jewellery bags are also suitable if you have limited space in your box.
Citrine is durable enough to survive the odd bump or knock on a hard surface; however, you should always take care to avoid such abuse. That is why it is always recommended to remove jewellery before physical activities, especially household cleaning or gardening.
Citrine can be safely, simply, and effectively cleaned with warm soapy water and a soft brush, such as a toothbrush.
